In this example the back wall is at 0.3m with a transmission time of 255
μs. If the aim were to look for variation in thickness it would be reasonable
to set the gate between 200 μs and 300 μs.
In the distance mode, the gate can also be set using the distance scale
at the top of the screen as an aid.
3.6 Measuring with Pundit PL-200PE
NOTE! Testing with Pulse Echo Technology requires in-depth
knowledge of the test object and application characteristics.
Proceq offers comprehensive ultrasonic training seminars
imparting this knowledge as well as all functionalities and
features of the Pundit instruments. Pundit PL-200PE users
are recommended by Proceq to register for the Advanced
Ultrasonic Tomography Applications training. Details can be
found on the Proceq website.
Preparation
• Very few preparations are necessary when measuring with the Pulse
Echo Transducer.
• The dry-contact transducer means that acoustic coupling is ensured
without the use of any couplant.
• The contacts are sprung and can accommodate surface irregularities
to a depth of 7 mm, so smoothing of the surface is also unnecessary.
• For Area Scans and B-Scans a test grid should be drawn out on the
surface. Alternatively Proceq provide a calibrated tape (Part No. 327
010 71) that can be stuck on the surface for the test and then removed
afterwards.
• For best results with Distance, Pulse Velocity and Area Scan measure-
ments make sure that Echo Tracking and Enable Gate are activated in
Settings.
